I am flying BSB-GRU (Domestic Latam) connecting with GRU-LAX (Latam International) and have 1 hour 50 minutes scheduled ground time at GRU between scheduled landing and scheduled departure. There is a mandatory security rescreening to enter Terminal 3 from the domestic side for the Intl flights. Is this enough time to make this connection? Will I be officially checked in when I board my flight in BSSB for the intl floght from GRU or am I only officially checked in after the terminal 3 rescreening checkpoint.
